McAfee researchers falsify a patient’s vital signs in real-time

McAfee’s security researchers announced at the Defcon hacker event in Las Vegas this week that they were able to hack into a medical network and falsify a patient’s vital signs.

There’s evidence for a number of processes, from potentially transient changes in gene expression, through long-term changes in DNA packaging, and up to alterations of the connections among cells. Complicating matters further, none […]

There’s actually some evolutionary logic to this. The bacteria can get transmitted to the eggs of the females they infect but […]

Army researchers find the best cyber teams are antisocial cyber teams
